Application filed October 13, 1906. Serial No. 282.685.

To all whom it may concern:

Be it known that I, WILLIAM E. MATTHEW,

a citizen of the United States, residing at Bu-,

cyrus, in the county of Crawford and State of Ohio, have invented certain new and useful Im rovements in Torpdoes; and I do hereby dec are the following to be a full, clear, and

exact description the invention, such as will enable others skilled in the art to, which.

it sippertains to make and use the same.

y invention relates to torpedoes of that character utilized by railroads for signal purposes; and its object is to provide a torpedo which is formedentirely of aper, which is of simple const' ction, and w 'ch does not require the use of any special means for securing the fastening-strip to the torpedo.

The invention consists of a substantially flat tubular envelop havin its ends slit, so that the same can be cause to interlock, and Within these slits is disposed a fastening-strip adapted to be placed in engagement with a rail. The ends of the envelop are adapted to be permanently secured by a suitable adhesive material, so that displacement of the parts will not occur.

The invention also consists of certain other novel features of construction and combination of parts which will be hereinafter more fully described, and pointed out in the claims.

' In the accompan g drawings I have shown the referred fb i m of my invention.

In said rawings, Figure 1 is a perspective view of my improved railway-to edo. Fig. 2 is a longitudinal section theret rough, and Fig. 3 is a detail view of the envelop.

Referring to the figures by numerals of reference, 1 is a substantially flat tubular envelop formed of pa er or other fibrous material, and opposite y disposed slits 2 are formed within each end of the tube, so as to produce tongues 3 and 4 at op osite ends of the envelo respectively. '1 1e tongues 4 are rounde and narrower than the tongues 3', so that the same may be readily inserted between said tongues 3 when the torpedo is folded.

In using the torpedo herein described the envelop is folded upon itself at about the point indicated by dotted line 5 in Fig. 3, and thetongue 3, contacting with said envelop, is then fastened in place by means of a strong glue. A quantit of explosive material 6 is then placed wit in the envelop, and the tongues 4 and the adjoining portion of the envelop are folded back on the dotted line 7 shown in Fig. 3. A fastening-stri 8, of soft metal, is then inserted between t e tongues 4, and saidton their ends by g no, and their outer faces are then also covered with adhesive material, after which said tongues 4 are inserted between the tongues 3 until es are fastened together at the strip 8 contained therebetween comes into contact with the ends of the slits formed between said tongues 3. All four tongues will then be held permanently fastened by the glue thereon, and the fastening-strip 8 will be securely maintained in roper position. The explosive contents 0 the torpedo are fully protected from moisture, because it becomes unnec essary with this arrangement to perforate the envelop, Moreover, no particular means other than glue are necessary for fastening the torpedo together after the same has been filled, and as a result an all-paper torpedo is formed.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-

1. A torpedo formed of a tubular envelop havin integral ton use at its ends, said envelop aving its ends folded upon itselfand its ton es interlocking and secured together, and a astening-strip interposed between and retained by the tongues.

2. 'A torpedo com rising a tubular envelop open at its ends an having integral tongues at said ends, said envelop having its ends folded upon itself and the tongues of one end extending between the tongues of the other end, all of said tongues being ermanentlv fastened together by an adhesive materia and a fastening strip extending between and retained by the ton ues.

3. An all-paper torpedo com rising a substantially fiat tubular envelop aving a pair of tongues at each end, the tongues of one end bein narrowerthan the remaining tongues, t e ends of the envelop adapted to fold inward and the tongues to mterlock, the narrow tongues pro'ecting into one end of the envelop when the same is folded, said held together by an adhesive tongues being material, and means extendlng between and retained by the tongues for securing the tor l at each end, an explosive material within the 1 IO inter ocking and secured by an adhesive ma- In testimony whereof I have signed my name to this specification in the presence of 4 two subscribing itnesses.
